Helianthella

Helianthella quinquenervis (P-1652)

Each 7.75

AVAILABLE SPRING 2021

<i>Helianthella quinquenervis</i>

The clearest, brightest yellow, not at all pale and without a trace of gold, imbues the nearly 4 in. wide starry flowers of this willowy American native. Amazingly floriferous and versatile, the Aspen Sunflower is lower growing and earlier to bloom than its Helianthus counterpart.

Long, green and hirsute, straplike basal foliage blushes red come fall, while seed heads, waving on open branched sparsely leafed stalks, provide a banquet for the birds.

Originally collected in 1843 and dwelling throughout woodlands and stream sides from the “Aspen Belt” north to Wyoming and Montana, it will thrive in nearly any garden—semiarid or moist, sunny or a little shady—and makes a fine autumn bouquet with grasses and rosehips.

Blooms July – September.

Size: 3' 0" – 4' 0" high x 2' 0" – 2-1/2' wide.

Hardy to zone 3.

Our Featured Plant: Crocosmia ‘Zeal Tan’

Captivating Crocosmias, Plants that Dodge to Dog Days of Summer, 2020 T-shirst have arrived!

Captivating Crocosmias!

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

Dodge the Dog Days of summer….

with plants that pack a punch of blooms and alluring leaves at this time of year. By late August, our borders can look a tad tired and may be in need of some sprucing up. Adequate moisture and an additional application of compost will ensure late summer vitality. You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes. 

All of us Digging Dog plant wranglers wish you Happy Digging and good health.
